• Electrical service & distributionNot in this windowNothing in the permit records we read for this parcel that names this system. Worth knowing: a 2025 addition / alteration permit is on file (and 1 more like it) — work like this is often folded into a larger permit without being named, so open that record and check its scope before concluding anything. That does not mean the gear is original — only that nothing has been permitted here recently. Where it matters is capacity: obsolete distribution lines carry breaker and fusible-switch lead times that turn an outage into a shutdown, and that is worth knowing before a new tenant or a new rooftop unit. Separately from replacement: NFPA 70E expects the arc-flash study to be reviewed at least every five years, or after any change to the service.
• Heating, cooling & mechanicalCurrentLast permitted 2025 (1 year ago). Packaged rooftop units work harder in Tucson than almost anywhere, so 12 to 15 years is a realistic service life rather than the 15 to 20 the industry quotes.

• Fire alarm & life safetyNot in this windowNothing in the permit records we read for this parcel that names this system. Any alarm or sprinkler work here predates this feed. For an occupied commercial building that is worth confirming from the panel and the inspection tags rather than assuming.
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system. Roof age matters electrically too: it sets what can be penetrated for new rooftop units, conduit, or solar.

A found permit means a lot. A missing one means less. This parcel is in unincorporated Pima County, so we read the county’s own permit system — including its historical permits, which reach back into the 1990s where they exist. Every record links to the county’s official file. A blank line does not say nothing was done: work gets done without permits all the time. The only way to know what is actually installed is to look at it.

What that usually means electrically

• Era-based check

  Gear in this age range is usually still supported but is due for infrared scanning and torque verification if that has not been done recently. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  NFPA 70E expects arc-flash studies to be reviewed at least every five years, or after any change to the service. Buildings this age often have labeling that no longer matches the installed gear. The permit record does not confirm this; an on-site inspection is required.

Permit history (16)

How to read the status column: Final / Complete / C of O — city records show the permit was finalized. Issued — the work was permitted, but final completion is not confirmed. Applied / In review / Approved / Fees paid — proposed, not completion. Expired — the permit expired without a confirmed final status. Void / Withdrawn / Canceled — not evidence the work was installed. Any other status is shown exactly as the issuing office records it, without a completion reading.

Record numbers link to the issuing office’s official file — Pima County’s portal for county permits, the City of Tucson’s for city records. Highlighted rows are the ones that imply electrical work or an unpermitted-work finding.

This is an inference from public records — the year a structure was built, how it is classified, and what has been permitted. It is not an inspection, and nothing here confirms what is actually installed at this address. The only way to know is to look in the panel.

The contractor’s read is a plain-English brief of the record above, written by AI — what it shows across electrical, mechanical and the building itself, what is missing for the era, and what to verify on site.
